STEP 1
Make four 3-inch vertical incisions through the rootstock's
bark, starting at the top. Slip a small rubber band on the root-
stock, stopping just below these vertical cuts. With the point
of a knife, separate the bark from the wood at the tip of the
rootstock. Peel the bark down in four 3-inch-long flaps. Cut
off an equal-sized piece of rootstock with shears after peel-
ing back the bark.
STEP 3
Prepare the scion by trimming 1/2 inch off the bottom to
show fresh, green wood. Slice a shallow, 2-inch cut into the
wood at the bottom end of the scion. This cut exposes cam-
bium tissue, which carries sap through the tree. Repeat this
in order to create four evenly-spaced cuts.
STEP 3
Place the cut end of the scion inside the four flaps, lining up
each cut surface with a flap.
STEP 4
Now is the time to use the rubber band to hold the flaps in
place. Make sure the cambium tissue of the scion is seated
against the cambium tissue of the rootstock.
STEP 5
Protect the graft by wrapping it with a piece of heavy-duty
aluminium foil, then a piece of plastic.
STEP 6
Tape the plastic lightly around the graft using masking
tape. New buds should appear in 15 to 30 days. You may want
to write the date and tree variety on the tape to keep track of
multiple trees.

Grafting is a horticultural technique that's defined as attaching a twig (scion) from one tree to the
stem of a tree seedling (rootstock). The scion becomes a permanent part of the tree over time. If the
scion is from an improved variety, the tree will take on those characteristics. There are several grafting
techniques, but today we choose to demonstrate their favourite technique, the four-flap graft technique.
